Hi Kate2 and Bud,

Thanks for your responses. For me, Zoloft was the absolute worst, and I lost a few weeks dealing with the symptoms. I actually got another concussion in January (about a month ago), and I think the Zoloft impeded my recovery.

Kate2 - I ordered a wrist HR monitor that was laughably bad, and upgraded to a chest monitor, and am now going on a few walks a day. Unfortunate, because I was doing sub-7 mile runs run beforehand, and now I'm sore the day after walking for 12 minutes. Baby steps!

Bud - oddly, I'm glad I'm not the only one who deteriorated for no reason after initial concussion. I'll be seeing a concussion specialist next week, and we'll see what else they identify. Although the exercise was the only thing that exacerbated my symptoms, I never felt quite right, so maybe there was some vestibular or visual stuff going on as well, and everything might be tied together.
